Application filed November 24, 1918. Serial No. 802,784.

State of Visconsin, iavo invented a new and Useful Carbureter andVaporizer, of which the following is a specification.

The present invention relates to improvements in carburetors andvaporizers, one object of the invention, being the provision orproduction of a single structure embodying both a carburetor andvaporizer or air mixer, the same being provided with auxiliary means forsupplying air in proportion to the fuol hefore the delivery of theproportional carbureted air to a mixing device, said mixing device beingso disposed as to be heated by the exhaust from the explosion engine sothat the roper vaporization and mixture of the car iiireted air will beproduced before introduction into the explosion chamber of the engine.

A still further object of the present invention is the combination withthe carhuretcd air mixer as shown in in U. S. Patent No. 1,002,670 datedScptem er 5, 1911, with means for properly producing a proportionedcarbureted air, so that such carbu reted air will be properly deliveredthrough the mixer after which the same is delivered to the explosionengine, there being provided heating means utilizing the heat from theburnt gases of the explosion engine for heating the mixer, so that thecarbureted' air will be properly heated before introduction to thecylinder. thus insuring the delivery of a perfect explosive mixture tothe explosion engine and eliminating all streaks before such delivery.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the comiimition andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings-Figure 1 is a vertical sectional view through thecomplete carbureter and va orizer. Fig. 2 is a section taken on the inc22 of Fig. 1. Fig. 3 is a section through the main air intake taken atright angles to the position as shown in Fig. 1. Fig. 4 is a rearperspective view of the complete carburetor and vaporizer.

Referring to the drawings, the numeral 1 designates the main air inletpi e which is lprovided with the butterfly or t rottling va ve 2, saidpipe leading into the enlarged chamber 3 carryin the valve seat port 4which is controlle by the spring closed puppet valve 5. This valve isrendered adjustable and is adapted to be opened due to the suctionaction of the explosion engine (not shown). A chamber 6 is provided andinto this leads the chamber 3 so that air may be properly deliveredtherein and into the annular chamber 7 formed by the depressed wall 8 ofthe float chamber or easing9. The inverted dome shaped member 10 isdisposed concentrically above the chamber 7 and receives the inrushingcarbureted air, insuring the delivery thereof through the channel 11into the mixing chamber 12, the main principal of whichcovcrs therotating fans and streak eliminating device as set forth in my beforementioned patent.

In order to properly heat the mixer and especially the channel portion11 before the delivery of the carbureted air to and through the mixer,the exhaust ipe 15 is connected to the jacket 16 while t 10 outlet 17thereof is connected with the continuation 15 of the exhaust ipe. Thusthe burnt charges from the exp osion engine may be directed to assist inthe vaporization and proper heating of the carbureted air durin themixing and delivery thereof through file mixer 12 to the explosionchamber.

The intake 18 by means of which the liquid fuel is supplied to the floatchamber 1 9 is controlled by the valve 19, the lever 20 being connectedthereto and actuated by the float 21. This float 21 is an annular memberand is disposed about the tapered sleeve 22 mounted centrally of thefloat chamber 9 and open both at its bottom and top ends, the upper endoutleting into the chamber 7 adjacent the inlet end of the chamber 10,

While the lower end is in communication till ' sion.

with the port 528 of the air supplying pipe 30, said pipe being held inposition by means ot the lock nut 29 threaded upon the downwardlyprojected threaded stem 27, Which is properly supported by the crossbars 23 within the lower end of the sleeve 22. Carried by the cross bar23 is the fuel supplying" nozzle :23 controlled by the verticallyslidable valve 2t. lhis valve is mounted for sliding movement within thesleeve 25 and has disposed upon its upper threaded end, the adjustingand controlling means 26, which is adapted to be operably connected toan automatic means operated by the explosion engine and here not shownAs is usual a butterfly valve 32 is disposed Within the primary or mainair supplying pipe 30 From the foregoing description taken in connectionWith the drawings, it is evident that there is combined here a singlestruc-.

ture embodying both. the carburetor and the carbureted air mixer orvaporizer so that the may be readily connected similarly to theconnection for carbureters of the present day, to the lower end of, theintake manifold of the explosionengine, and thus combine in a unit thetwo essential mechanisins for delivering to the explosion chamber of theengine, a properly mined carbureted air and. one by means of which themaximum power is obtained at each enplo lit will also be noted that bymeans of the air inlets l and it, that Warm or cold air or aproportionate mixture of the same end of the rust nozzle beingslightly'below' the upper end of the tube, an airsupply conduitcommunicatio With the u er end of the tube thereof, an inverted domeshaped member disposed above and in spaced relation to the upper end ofthe central tube of the liuel chamber for receiving the explosivemixture, a conduit leading from said dome for connection to the intakemanifold of an explosion engine, the air intake pipe being provided withtwo branches for sup: plying Warm and cold air, and a valve disposed inthe said pipe at the junction of the two branches for controlling thesupply of either the hot or cold air or a combination of the twoto thecarburetor.

2. A carburetor, including a float con trolled tuel chamber having acentrally disposed tube open at both ends, a fuel nozzle disposedcentrally within the tube and reicence ceivinp; fuel from the chamber,the upper end oi the fuel nozzle being slightly below the upper end oithe tube, on air supply conduit communicating With the upper end of thetube thereof, an inverted dome shaped member disposed above and inspaced relation to the upper end of the central tube of the fuel chamberfor receiving the explosive mixture, a conduit leading from said domefor connection to the intake manitold of an explosion engine, the airintake pipe being provided with two branches for supplying Warm and coldair, a valve dis posed the said pipe at the junction of the two branchesfor controlling the supply of either the hot or cold air or acombination of the two to the carburetor, and an auxiliary air supplyingconduit in communication with the lower end of the central tube oi thefuel chamber.

3. A carbureter, including a incl chamber having a. centrally disposedtube open both ends, a fuel nozzle disposed centrally Within the tubeand terminating at a point below the upper end thereof, a slidablymounted valve for controlling the outlet of the nozzle, the portion ofthe chamber above the outlet end of the tube being depressed to form acup, an air supplying conduit leading from above and in communicationwith said cup, an inverted cup shaped member of lesser diameter than thedepression of the fuel chamber disposed above and in spaced relationfrom the depressed portion of the fuel chamber, and forming an outletand directing means for the carbureted air, a conduit leading fromthecup shaped member to direct the carbureted air to the manifold of anexplosion engine, and a valve controlled conduit in communication Withthe lower end of the central tube at the fuel chamber for controllingthe supply of air thereto.
